HOT-AIR ATTACHMENT FOR STOVES.

SPECIFICATION forming part of Letters Patent N O. 71 1,053, dated October 14, 1902.

Application filed February 17, 1902. Serial No. 94,445. (No model.)

To n/ZZ whom t may concern.-

v`Se it known that I, JOHN O. KINLEY, a citi- Zen of the United States, residing at Richmond, in the county of Vayne, and in the State of Indiana, have invented and produced a new and useful Improvement in Hot-AirAttachments for Stoves, of which the following is a specification, which is sufciently clear and concise to enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to hot-air attachments for stoves, and has for its object the provision of an arrangement of the several parts thereof whereby air of a low degree of temperature is drawn therein and discharged therefrom at a higher degree of temperature.

Another object is the provision of an attachment to be used in connection with ordinary stoves or furnaces whereby cool air is taken by the action of the heat in the stove from underneath the stove near the floor or from any other point on the door of a room, passed through the fire-space in the stove, and then discharged therefrom at a high degree of temperature into the same or another room or into a room above.

Another object is to provide means for equalizing the temperature in all parts of a room with a minimum of fuel.

Another object is to utilize a portion of the heat from a stove that otherwise would pass out through the flue in drawing the cool air from various parts of the room and then returning it again at a higher degree of temperature; and another object is the provision of an attachment, as specifically described otherwhere herein, which in addition to accomplishing the above-enumerated objects will be neat and attractive in appearance, positive and effective in its operation, and which can be manufactured and sold at a very low price.

Other objects and advantages will appear from the following specification and from the drawing forming a part thereof.

The invention consists in hot-air attachments for stoves embodying certain novel features and details of construction and relative disposition of the several parts, as hereinafter particularly set forth, illustrated in the drawing, and incorporated in the claims hereunto appended.

IlVith the above-eno merated objects in view I will now refer to the accompanying drawing, which forms a part of this specification, which is a view of a vertical section of my attachment and its relative position-With reference to a stove and the Hoor of a room.

In the drawing the numerals refer to the various parts of my invention and the letters refer to the parts shown simply to illustrate the relative locations of the various parts of my invention.

a and ct represent the sides of an ordinary stove, l) the top, and c the bottom thereof.

d represents the vent for the escape of smoke and gases from the stove into the line.

e represents the floor of a room on which the stove rests, and X represents the respace in the stove.

Referring now to my invention, l0 represents a drum, preferably of one piece of material-such, for instance, as metal tubingwith threaded ends and a threaded aperture in the center of a size sufficient to receive the threaded lower end of the pipe 22.. Each end of the drum l0 is provided with reducing-fit tings 11 and ll, which fit over the ends of lO, respectively. The outer ends of 1l and 11 are threaded on the outside, to which are secured the elbows l2' and l2", as shown.

13 and 13 represent perpendicular pipes with threaded ends, the upper ends fitting into the respective elbows l2 and 12", as shown. The threads on the lower ends of 13 and 13" continue twice the distance on the pipes as do the threads on the upper ends thereof.

14' and 14 represent lock-nuts surrounding the respective pipes 13 and 13" and rest on the upper surface of the bottom c of the stove.

l5f and l5" represent couplings which are screwed on the lower ends of the respective pipes 13 and 13" and engage the under surface of c.

16' and 1li" represent inverted funnels terminating in threaded nipples, which are screwed into the respective couplings l5 and l5".

In assembling the above-enumerated parts I first take the drum 10 and screw onto its IOO ends the redncers 1l and ll". I then screw the elbows l2 and l2" onto the ends of the respective reducers. The upper ends of the pipes 13 and 13" are then screwed into the elbows 12' and 12". The lock-nuts 14 and 14" are then screwed onto the lower ends of 13 and 13". I then pass the lower ends of 13' and 13 through corresponding holes provided inthe bottom c of the stove for that purpose, so that the lower ends of I3 and 13" will project through the bottom c. The couplings 15' and 15" are then screwed onto the lower ends of 13' and 13" until they contact with the bottom c. The funnels 16' and 16" are then screwed into the respective couplings 15 and l5, and I then screw the lower end of the pipe 22 into the aperture in the center of the drum lO, when the device will beready for operation.

It will now be apparent that should a re be maintained in the space X the pipes I3' and 13" and the drum l0 will be heated thereby and without interfering with or detracting from the usual amount of heat radiating to the sides and top of the stove. As the parts of my attachment located inside the stove become heated the air therein becomes heated and will passup through the pipe 22 into the room at a point above the stove or elsewhere to wherever the pipe 22 may lead. The hot air passing upward, as stated, lthe cool air from below the stove will be taken up through the funnels to take its place, and a circulation will thus be established and will be maintained as long as the drum and the pipes are warmer than the air at the inlets.

Myinvention is perfectly adapted to accomplish the results for which itis intended, and it is evident that changes in and modifications of the specific construction herein shown and described may be made and that analogous parts may be used to accomplish the same results without departing from the spirit of my invention or sacrificing any of its many advantages, and the specific construction of The details of my invention in which novel features are embodied may be variously changed without altering the essential principles, which are claimed as new.

Having shown and fully described my invention, what I claim, and desire to secu re by Letters Patent, is- Y l. A hot-air attachment for stoves comprising a horizontal drum lO, located in the upper portion of the lire-space of a stove, in combination with the reducing-fittings 1l and l1 attached to each end of the drum, the elbows 12 and 12" attached to said reducingfittings, the perpendicular pipes 13 and 13" secured in the said elbows and extending down through the bottom ot the stove and held rigidly in place by the lock-nuts 14 and 14 resting on the upper surface of the stovebottom in connection with the couplings 15' and 15" pressing in the opposite direction against the bottom of the stove, all substantially as shown and described.

2. A hot-air attachment for stoves comprising an exit-pipe 22 and a horizontal drum 10, located in the upper portion of the fire-space of a stove, in combination with the reducingfittings Il. and Ill attached to each end of the drum, the elbows l2 and 12 attached to said reducing-ittings,the perpendicular pipes I3 and 13" secured in the said elbows and extending down through the bottom of the stove and held rigidly in place by the locknuts 14/ and 14 resting on the upper surface of the stove-bottom in connection `with the couplings l5 and 15 pressing in the opposite direction against the bottom of the stove, all substantially as shown and described.

3. A hot-air attachment for stoves comprising a horizontal drum IO, located in the upper portion of the fire-space of a stove, in combination with the reducing-ttings 1I and 11 attached to each end of the drum, the elbows 12 and 12H attached to said reducing-fittings, the perpendicular pipes 13 and 13" secured in the said elbows and extending down through the bottom of the stove and held rigidly iu place by the lock-nuts 14' and 14 resting on the upper surface of the stove-bottom in connection with the couplings 15' and l5 pressing in the opposite direction against the bottom of the stove and receiving-funnels 16' and 16 suspended from said couplings, all substantially as shown and described.

In testimony whereof I have hereunto subscribed my name in the presence of two slibscribing witnesses.

JOHN C. KINLEY.
